[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0022] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0023] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0024] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0025] like Figures 1 to 5 As shown, a new type of portable toolbox suitable for installation on rail vehicles includes a box body 1, a telescopic component 2 connected to the box body 1, and a support leg 3 connected to the telescopic component 2. The telescopic component 2 is used to drive the support leg 3 to extend or retract.

[0026] In this embodiment, the telescopic component 2 is connected to the housing 1, and the support leg 3 is connected to the telescopic component 2. The telescopic component 2 is used to extend or retract the support leg 3, improving the convenience of height adjustment of the housing 1 and enabling the housing 1 to meet the operating posture of the operator. This solves the problem that existing fixed-height toolboxes cannot flexibly adapt to the needs of different maintenance positions and operating postures, making it extremely inconvenient for operators to retrieve tools, and that maintaining an uncomfortable posture for a long time can easily lead to physical fatigue and strain.

[0027] In some embodiments, the four corners of the housing 1 are connected to sliding cavities 4.

[0028] In some embodiments, the telescopic member 2 includes a sliding rod 5 slidably connected to the sliding cavity 4, and the support leg 3 is connected to the bottom of the sliding rod 5.

[0029] In some embodiments, the sliding rod 5 is hollow inside.

[0030] In some embodiments, the hollow sliding rod 5 is connected to a spring 6, and the other end of the spring 6 is connected to the sliding cavity 4.

[0031] In some embodiments, a nut 7 is connected to the housing 1, and the nut 7 is correspondingly arranged with the sliding cavity 4.

[0032] In some embodiments, the sliding rod 5 is provided with a snap-fit ​​groove 8, and the nut 7 is threadedly connected with a screw 9, which is used to abut against the snap-fit ​​groove 8 when tightened.

[0033] Example 1:

[0034] The housing 1, as the main body of the entire device, has pre-machined mounting holes or grooves at its four corners. The sliding cavity 4 is connected to the four corners of the housing 1 by welding, bolting, or other methods. For example, on the outer sides of the four corners of the housing 1, bolts are passed through the mounting holes on the housing 1 and the corresponding holes on the sliding cavity 4, and then tightened with nuts to ensure that the sliding cavity 4 is securely installed on the housing 1. The sliding rod 5 in the telescopic component 2 is the main telescopic component, and its shape is adapted to the internal space of the sliding cavity 4, allowing it to slide freely within the sliding cavity 4. The sliding rod 5 is inserted into the corresponding sliding cavity 4 to achieve a sliding connection between the sliding rod 5 and the sliding cavity 4. At the same time, the support leg 3 is fixed to the bottom of the sliding rod 5 by welding, riveting, or bolting. For example, a threaded hole is machined at the bottom of the sliding rod 5, and a connecting post with external threads is provided at the top of the support leg 3. The connecting post of the support leg 3 is screwed into the threaded hole at the bottom of the sliding rod 5, so that the support leg 3 is firmly connected to the sliding rod 5. Since the sliding rod 5 is hollow inside, when installing the spring 6, first place one end of the spring 6 inside the sliding rod 5, then connect the sliding rod 5 to the sliding cavity 4. At this time, connect the other end of the spring 6 to the corresponding position inside the sliding cavity 4 by welding, gluing, or setting a fixing hook, so that the spring 6 is in a stretched or compressed state, providing elastic force for the extension and retraction of the sliding rod 5. On the housing 1, corresponding to the position of each sliding cavity 4, install the nut 7 by welding, threaded connection, etc., ensuring that the threaded hole of the nut 7 corresponds to the position of the sliding cavity 4, which facilitates the subsequent installation and use of the screw 9. On the outside of the sliding rod 5, a snap-fit ​​groove 8 is machined according to the design requirements. The shape and size of the snap-fit ​​groove 8 are adapted to the end of the screw 9. Pass the screw 9 through the threaded hole of the nut 7, so that the screw 9 can rotate on the nut 7.

[0035] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0036] The telescopic component is connected to the box body, and the support legs are connected to the telescopic component. The telescopic component is used to extend or retract the support legs, improving the convenience of box height adjustment and allowing the box body to meet the operating posture of the operator. It solves the problem that existing fixed-height toolboxes cannot flexibly adapt to the needs of different maintenance positions and operating postures, making it extremely inconvenient for operators to retrieve tools, and causing physical fatigue and strain due to maintaining an uncomfortable posture for a long time.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
